We first developed this cleaning process over five years ago to cure the many sticky valves we saw in our repair department. We found that about 70% of all sticky valves were fixed by this 3 step process. For the few that continued to stick, the cause was mechanical and required our brass technician to repair. For most musicians, this treatment will save you a costly repair bill. There is enough for 1 treatment of 3 trumpet valves or 1 French Horn valve.

It is not necessary for you to take apart your valve assembly. First step is to run hot water through your horn. Move the valve repeatedly while water is going. Second, blow out all the water. You may have to take your slides off and blow again. With the slides off let your French Horn dry for 1 hours. After one hour of drying you are ready to start with Part A.

Lay your instrument on a clean towel. Take out the sticky valve by unscrewing the valve cap on top. If you are doing more than one valve we urge you to keep them in order. With a clean lint free cloth wipe off all oil or sludge from the valve. Remove the bottom cap of the valve and fish the cloth through the inside of the valve housing.

Liberally apply and rub onto the valve Part A. Apply liberally to the inside valve housing as well. Put the valve back inside the valve housing, making sure you have the valve guides aligned properly. Usually, one valve guide is wider than the other. The Cleaner in Part A is thick and your valve will move sluggishly. This is expected. Move the valve up and down several times. Your trumpet valve must soak in PART A for at least 24 hours. We recommend letting the valve soak 48 HOURS for better results. THERE IS NO WAY TO HURRY THIS STEP. Move the valve up and down occasionally during the soaking time. For French Horns: remove the slides by the valve and liberally drip Part A onto the valve area. Move the valve open and closed while adding Part A. Let soak for 24-48 hours and occasionally move the valve open and close.

Remove the valve from the trumpet. Wipe off with a clean cloth. Wipe inside of valve housing with clean cloth. (Do not use paper towels. Paper will only leave paper fibers on your valve.) Next Flush the inside of the valve housing and the valve with Part B. Wipe clean again. For French Horns: remove the slides by the valve and flush valve with Part B. Move the valve open and closed and add more drops of Part B. Use entire bottle of Part B for flushing.

Take two or three drops of Trumpet Juice Valve Oil and rub it onto the valve. Put two or three drops into the valve housing as well. Make sure it dribbles down the sides. Reassemble the valve making sure you have the valve aligned properly. Move the valve up and down. It should move freely. For French Horns: Use 1- 2 drops down each slide around the problem valve. Open and close valve after each drop. Your valve should now work freely.

IF YOU VALVE IS STILL STICKING YOU NEED TO HAVE A TRAINED TECHNICIAN REPAIR YOUR INSTRUMENT.

We recommend 1 or 2 drops of Trumpet Juice after every playing. Be sure to work the valves up and down after oiling. Do not over oil. Too much oil in the valve housing will cause suction affect and cause stickiness. We do not recommend using any other valve oil. Most have low viscosity properties which will not prevent sticky valves.
